You Will Need:
Nails (Purchase nails about as thick and long as a pencil or pen.)
Clips (High thickness wire cutters.)
Metal File (Durable)
Step One:
Cut all the heads off the Nails.
Step Two:
Proceed to file the cut ends into points(I suggest you make points on both ends).
Step Three:
Paint all the Nails to camouflage.
Is that simple or what? That is all it takes, about ten minutes to do five.
You can use these for many different things.

Buy a thin 4' bar stock at Sears, or a couple screws, grind down points on them,
hold a torch to the tip until it turns dark red, and quench it. Then, put it
in your oven for 2hrs under 400 degrees(tempering). It will have a nice gold
color. Just a suggestion.
Top
Quality Bo Shuriken
1) First, cut the bar stock to desired length(s).
2) Second, grind up to 2 or 3 inches from the point(or more, depending on thickness
of steel). Always keep a can full of ice water around to cool the piece off,
and use a towel or gloves to prevent it from burning your hand. You may also
grind the other end rounded to strike with, or to use acupressure on yourself.
3)
Rough finish.
4)
Next, grind it down perpendicular to the rough grinding. It should now be parralelle
with the spike.
6)The grain must now be finer in order to reduce brittleness. To do this, it
has to be normalized. Simply heat the bo shuriken to critical and let it cool
in the air. Repeat this process 4 times.
7) Time for heat treat. You can use a forge, but a torch is much easier to light,
and costs less too.
8) Quench in cold water(it is too thick of a piece to crack). And be sure to
NOT hit the bottom of the can, or the tip will bend from brittleness. Keep it
in there until it cools completly.
9) After the quench (oh baby, look at her! lol)
10) Time for tempering. Check out www.engnath.com/
for tempering ranges for different types of steel. Prop the spike between the
grate so that it sticks up in the air and heats evenly. Leave it in for about
2hrs under the recommended temp and leave the oven door closed so that it will
cool more slowly.
11) After tempering, rub the bo shuriken with metal polishing cream. Then, coat
it in baking soda with water and shrub off any oil or dirt as best as you can
(and don't touch it with your fingers). Put a clean cloth in the vise and clamp
the spike end of the bo shuriken. Apply gun blue with a clean cloth and let
it dry. It should have a foam growing on it afterwards, but can easily be wiped
off with a clean towel. If some parts are faded, clean it up again and apply
more bluing
